B. Roof Preparation
1.
FIRE OR ELECTRICAL SHOCK
HAZARD. Verify there are no obstacles inside
boat’s roof and/or walls (wires, pipes, etc.). Shut
OFF
gas supply, disconnect 120 Vac power
from boat, and disconnect positive (+) 12 Vdc
terminal from supply battery
BEFORE
drilling or
cutting into boat. Failure to obey these warnings
could result in death or serious injury.
2. Carefully mark and cut the required roof open-
ing. See section, "C. Roof Requirements" on
page (4).
3. Using the roof opening as a guide, cut the match-
ing hole in the ceiling.
4.
Maintain structural integrity. Oth-
erwise damage to product and/or boat could
occur.
NEVER
create a low spot on boat
roof. Otherwise, water will pool and could cause
a leak.
The opening created must be framed to pro-
vide adequate support and prevent air from be-
ing drawn from the roof cavity. Framing stock
19 mm or more in thickness must be used.
Remember to provide an entrance hole for
power supplies at the front of the opening. See
(FIG. 3).
INSTALLATION INSTRUCTIONS
A. Choosing Proper Location For Unit
This unit is specifically designed for installation on the roof
of a boat. Mount only with front of unit facing the bow (the
vented end should face aft). See (FIG. 4).
When determining your cooling requirements, the following
should be considered:
●
Size of boat;
●
Window area (increases heat gain);
●
Amount of insulation in walls and roof;
●
Geographical location where boat will be used;
●
Personal comfort level required.
It is preferred that the unit be installed on a relatively
flat
and level roof section, but up to a 15° tilt is acceptable.
1.
After location has been selected:
a. Check for obstructions in the area where unit
will be installed. See (FIG. 1).

b.
Maintain structural integrity.
Otherwise damage to product and/or boat
could occur.
The roof must be designed to support 60
kg when the boat is in motion. Normally
a 91 kg static load design will meet this
requirement.
c. Check inside the boat’s cabin for air distri-
bution box obstructions (i.e. space for doors
to open, room dividers, curtains, ceiling fix
-
tures, etc.). See (FIG. 2).
